Section 1

General Information

Intr

oduction

The Baldor Series 23H PWM control uses flux vector technology. Flux vector technology is a closed

loop control scheme using an algorithm to adjust the phase of voltage and current applied to a three

phase permanent magnet synchronous motor. The servo control separates the current into it's flux

and torque producing components. They are independently adjusted and vectorially added to

maintain a 90 degree relationship between them. This produces maximum torque from base speed

down to and including zero speed. Above base speed, the flux component is reduced for constant

horsepower operation.

The control should be sized to the motor using the rated output current of the control.

The Baldor Series 23H control may be used in many different applications. It may be programmed

by the user to operate in four different operating zones; 2.5 KHz PWM or 8.0 KHz PWM constant

torque or variable torque. It can also be configured to function in a number of modes depending

upon what the application requires and user preference.

It is the responsibility of the user to determine the optimum operating zone and mode to interface

the control to the application. These choices can be made through the keypad on the face of the

controller as explained in Section 3 of this manual.

Section 2

Installation

This section covers all instructions for proper mounting and wiring of the Baldor Series 23H servo

control. All tools required for normal installation should be available from any electrical service

technician. If problems arise after installation, please refer to Section 4 Diagnostics and

Troubleshooting.

Location and Mounting

Select a mounting surface for the control that will allow the control to be mounted in a vertical

position using the mounting holes provided. The area selected should allow for free air circulating

around the control. Provide for at least two inches of clearance on all sides for maximum cooling

efficiency.

CAUTION: AVOID LOCATING CONTROL IMMEDIATELY ABOVE OR BESIDE HEAT

GENERATING EQUIPMENT, OR DIRECTLY BELOW WATER OR STEAM

PIPES.

The control is designed for panel mounting. Mount in a clean dry enclosure with an ambient

temperature less than +40 deg C. DO NOT mount control above transformer or other sources of

heat. DO provide 2" minimum clear area above and below the control to allow free flow of air over

heatsink on the back of the enclosure.

Provide access to the front of the enclosure to adjust parameters and to observe the keypad. Allow

room to remove the front cover to gain access to the power components. Mounting dimensions are

provided in Section 5.

ALTITUDE DERATING: Control ratings apply to 3300 feet (1000 meters) altitude without

derating required. For installations at higher altitudes derate the

continuous and peak output currents of the control by 2% for

each 1000 feet above 3300 feet.

TEMPERATURE DERATING: Control ratings apply to 40°C ambient. Derate output by 2%/°C

above 40°C, up to a maximum of 60°C.

Main Cir

cuit Wiring

Inter-connection wiring is required between the vector control, AC power source, host controller and

any optional control stations. Use UL Listed closed loop connectors sized for the wire gage involved.

Connectors are to be installed using the crimp tool specified by the connector manufacturer.

CAUTION: SERIES 23H CONTROLS FEATURE UL APPROVED ADJUSTABLE MOTOR

OVERLOAD PROTECTION SUITABLE FOR MOTORS NO LESS THAN 50%

OF THE OUTPUT RATING OF THE CONTROL. OTHER GOVERNING ENCIES

SUCH AS NEC MAY REQUIRE SEPARATE OVER-CURRENT PROTECTION.

SEE APPENDIX E FOR MAXIMUM AC LINE SHORT CIRCUIT CAPACITIES

FOR ALL CONTROL CATALOG LISTINGS.

AC Line Impedance

The Baldor Series 23H servo control requires a minimum line impedance of 3%. If the incoming

power line does not have a minimum of 3% impedance, the addition of a line reactor will provide the

needed impedance in most cases. Use the formula below to calculate the size of the line reactor you

must provide. Line reactors are available from Baldor. Note: Continuous input currents for Series 23H

controls provided in Table 2.0 which follows.

L = (V L-L x .03) / (I x 1.732 x 377)

Where: L = minimum line inductance in henrys

V

L-L = input voltage measured from line to line

.03 = desired percentage of impedance

I = the continuous input current rating of the control

1.732 = square root of three

377 = constant used if the input frequency is 60 Hz. Use 314 if the Input

frequency is 50 Hz.

The controller is self protected from normal AC line transients and surges provided input impedance

from the AC line is at least 3% (voltage drop at the input is 3%minimum when the control draws

rated input current). Additional external protection may be required if high energy surges are present

on the incoming power source. These surges could be caused by sharing a power source with arc

welding equipment, large motors being started across the line, or other industrial equipment

requiring large surge currents. To prevent control damage due to power source disturbances the

following should be considered:

a. Connect the control on a feeder line with a line impedance of 3% minimum.

b. Supply power to the control through a 3% minimum impedance line reactor or

transformer.

Line reactors serve several purposes:

1) minimize voltage spikes from the power line that may cause the control to trip on over-

voltage spikes.

2) minimize voltage harmonics from the control to the power line.

3) provide additional short circuit capability at the control.

CAUTION: DO NOT USE POWER FACTOR CORRECTION CAPACITORS ON THE INPUT

POWER LINES TO THE CONTROL OR DAMAGE TO THE CONTROL MAY

RESULT.

AC Power Connections

The control requires input power protection in the form of either a circuit breaker or fuses. Circuit

breakers are recommended. See Table 2.1 for fuse and breaker sizing. Connect the fused three

phase AC power lines to the input power terminals L1, L2, and L3. The phase rotation of the

incoming power source is unimportant as the control is not phase sensitive.

Wiring and Protective Devices

This control must be provided with a suitable input power protection device. Use the recommended

fuses or circuit breaker listed in Tables which follow. Input and output wire size is based on the use of

75 degree C rated copper conductor wire. The table is specified for NEMA B motors.

Circuit Breaker 3 phase, thermal magnetic. Equal to GE type THQ or

TEB for 230 VAC or GE type TED for 460 VAC.

Fast Action Fuses Buss KTN on 230 VAC, Buss KTS on 460 VAC or equivalent.
